Solana indexing of transactions in blocks and their filtering for necessary data
It is necessary to receive a stream of all Solana blocks and analyze transactions inside to extract:
1. The prices of all tokens available on coingecko in the Solana network and constantly update the price database after each block. Also, obtain the token database through the public API from coingecko. Then implement tracking of significant price changes after swaps.
2. Track large token transfers, for example, over $50k
3. Track large mints and token burns
4. Track large liquidity additions and removals
5. Repeated sales and purchases of a token from one wallet
It is preferable that the code does not consume too many requests from the RPC, minimizing them.

It is interesting that you want to optimize processes with minimal use of resource-intensive queries. I specialize in developing solutions for indexing and filtering that provide accurate data without unnecessary loads on systems. To obtain data from Solana and CoinGecko, I will apply approaches that effectively process information in real-time. My experience in automating business processes and administering databases guarantees the reliable operation of your project. I am ready to discuss the details and the optimal way to solve it!

The project is interesting, but I will note right away: essentially, this is a Solana on-chain indexer + event analytics (whale alerts / swaps / liquidity / mint-burn) with a requirement for minimal load on RPC.
I can implement a solution with the right architecture for your task:
• A stream of transactions/slots through WebSocket (and if possible through Geyser/Yellowstone gRPC — this is the best option for “all blocks” without overloading RPC);
• Decoding transactions and extracting events:
• SPL transfers (whales $50k+),
• mint/burn,
• swaps and liquidity (Raydium/Orca for MVP, then expanding to other DEX);
… • Price layer:
• A list of tokens through the public API CoinGecko,
• Price cache and updates for active tokens / on-demand, to avoid hitting limits,
• Calculation of USD valuations and detection of “strong movements after a swap”;
• Storage and analytics (PostgreSQL/ClickHouse), alerts in Telegram/Discord/HTTP.
Before estimating costs/timelines, I will clarify 3 points:
1. Do you have access to Geyser/Yellowstone or dedicated RPC (Helius/Triton/QuickNode, etc.)?
2. Which DEX are mandatory in the MVP (is Raydium/Orca sufficient?)
3. Where to send alerts and how to store history (dashboard/bot/api)?
If that’s okay — I will propose a roadmap and we will start with an MVP that will not “consume” RPC.
